Serial NO. 436,155.

This invention relates to means for closing the circuit of a lighting system by an alarm clock, the general object of the invention being to provide a switch rotated by the turning key of the alarm mechanism of the clock when the alarm mechanism is in operation so that the lights can be turned on whenever desired by setting the alarm mechanism to operate at the desired time.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation with parts in section, showing the invention in use.

Figure 2 is a section on line ,2--,2 of Figure 1. I

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a view similar to Figure 3, but showing the handle plate removed and the parts in section.

Figure 5 is a view similar to Figure 4, but showing the rotary member removed.

Figure 6 is a section on line 6-6 of ure 5.

Figure 7 is a View of the handle plate.

In these views, the numeral 1 indicates an angle shaped support, the horizontal part supporting the alarm clock A and the vertical part having attached thereto the switch B. This switch comprises a block 3 of non-conducting material which is attached to the-support by the screws 4: and said block is formed with a circular recess 5 in the face next to the clock, the side wall of which is provided with a groove 6 in which is placed a pair of metal rings 7 the rings being separated by a strip 8 of non-conducting material. The rings are split and one end of one ring is connected to a terminal 9 and an end of the other ring is connected to a terminal 10. A circular block 11 is rotatably supported in the recess 5 by a Figscrew and a spring pressed ball 13 is arranged in a socket formed in a part of the edge of said block 11. The spring tends to 'force the ball against the rings so that it will bridge the rings and thus complete the circuit between the rings. When the circular mem ber 11 is in a position with the ball 13 at the bottom thereof, the ball will be out of engagement with the rings as the ends of the rings are spaced apart for this purpose. I

A cover plate 14 is attached to the block 11 i by the screws 15 and said cover plate is formed with 'a'handle 15', which when the ball 13 is located in the space between the ends of the rings, will be in a depending position, as

shown in Figure 3, so that this position of the handlewill indicatethat the circuit is broken. A conductor 16 is connected with the terminal 10 and a conductor 17 is connected with the terminal 9. A conductor 18 1 and theconductor 17 pass through apassage '19 in the block 3 and through a'tube 20, the

conductors being connected with a lamp 21 at the free end of the tube. This tube is connected with the upper part of the block 3, as

shown in Figure 1.

The block 11 has a slot 22 therein and the plate 14 has a slot 23 therein which registers with the slot 22 and these slots are adapted to receive the winding key 24 of the alarm mechanism of the clock so that when the alarm mechanism is in operation, the turning movement of the-key will be imparted to the block 11 and the plate 14. This movement of the block 11 will cause the ball 13 to engage the rings 7, thus bridging the same and completing the circuit to the lamp .or lamps and the circuit will remain closed until the member 11 makes a revolution, when the ball will ride oil the ends of the rings and thus the circuit will be broken. Of course, if the alarm mechanism continues to operate, the ball will again engage the rings and turn on the lights for another revolution.

If it is desired to keep the lights burning, a pin 25 is placed in one of a pair of holes 26 in the member 3 so that said pin will engage the handle 15 and thus stop further movement of the parts so that the parts will remain in a position with theball 13 bridging the rings '7 and thus the circuit Will remain closed.

From the foregoing it Will be seen that I have provided simple means for controlling a circuit by the alarm mechanism of a clock so that the circuit can be closed at any desired time by setting the alarm mechanism to operate at such time.

While l igure 1 shows a single lamp ar ranged to illuminate the face of the clock, it

will, of course, be understood that the device can be arranged to control the circuit of a plurality of lamps placed in any desired vositions.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the com bination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

What I claim is Means for controlling a circuit by an alarm clock comprising a support having a circular recess therein, a pair of ring contacts carried by the support and insulated therefrom and from each other, each contact having its ends spaced apart, a circular member of non-conducting material rotatably arranged. in the recess, a brush carried by the member for engaging the ring contacts, said circular member having a slot therein for receiving the windingkey of the alarm mechanism of the clock, a cover plate connected with the circular member and having a slot therein through which a part of the key passes and a handle formed on the cover plate.

In testimony whereof I aiiix my signature.
